Israel Idonije stood under a ceiling of roughly 100 soft, circular light fixtures on a Thursday night in mid-September, watching people who used to drink at M Lounge walk back through the same door on South Wabash. One of them, a news producer who lives a few blocks away, told Block Club Chicago the room felt bigger than he remembered it. The chairs were new, plush green with zebra print, the lighting low enough to read as film noir. The Miles Davis portrait that had hung over the bar for twenty years was still there, moved but not removed.
The space had been closed for the better part of a year. Reginald and MaryAnn Marsh ran it as M Lounge for two decades before handing operations to Idonije's Pangea Restaurant Group last fall. In April, Idonije told Block Club he was aiming for a June reopening under the new name Martini Lounge. June came and went. The doors didn't open until the second week of September, quietly, with no formal announcement until the preview event three weeks ago.
That three month gap between promise and delivery is worth sitting with, because it tells you more about what's actually happening on this stretch of the South Loop than the reopening itself does.
The Corridor Didn't Wait Around for One Bar
While Martini Lounge sat dark, the neighborhood didn't. Buttercup opened at 75 E. 16th St. in September 2025, run by the same Pangea group but built around a different idea: Idonije looked at Chicago's bar landscape, found only one other spot built specifically around amaro, and decided that gap was worth filling a few blocks from where he lives. Chef Alex Carnovale, who also cooks at nearby Oliver's, handles a menu that includes truffle pizzettas and pistachio cake. Designer Nathan Michael gave the space butter yellow walls and lace curtains that read as an Italian café in the morning, when it's pouring Sparrow coffee, and shift into a cocktail bar by evening.
A few blocks over on Michigan Avenue, Brûlée opened in November 2025 under chef Emani Nicole Roberts, who spent years cooking privately before her mother pushed her toward a full restaurant. None of these three, Buttercup, Brûlée, or the relaunched Martini Lounge, is a satellite location of something that started in River North or the West Loop. They're independently built, within about six blocks of each other, by people who already had a stake in this stretch of the South Loop before any of them opened a register.
That matters for anyone who already lives here and has spent the past few years driving north for a decent cocktail. It also matters because it changes how you should read everything else Idonije has said is coming.
Why "Planned for 2026" Deserves Some Skepticism Right Now
Idonije isn't done. He's confirmed two more concepts for the corridor: a high-end Japanese cocktail lounge and Happy's Classic Ice Cream at 69 E. 16th St. Both were announced earlier this year with no firm open date attached. He's also converting the former Hudson Motor Building at 2222 S. Michigan Ave., on Motor Row, into a 154-room boutique hotel that's expected to operate under Hilton's Curio Collection, with a restaurant and event space built in. Stephen Gillanders, who partnered with Idonije on an earlier steakhouse concept in the same stretch, is involved in that project too.
Here's the part worth remembering before you start checking the ice cream shop's Instagram every week: Martini Lounge was supposed to open in June. It opened in September. That's not a knock on Idonije's operation, it's a pattern. His first attempt at a restaurant in this corridor, Signature Steak at 1312 S. Wabash, closed in February after about a year, roughly a year after he'd rebranded it into that concept in the first place. Ambitious builds on this stretch of Wabash and Michigan have consistently taken longer, and sometimes gone through more than one version, before they land.
None of that undercuts the hotel plan. A 154-room hotel doesn't get built without dining and nightlife already working in the surrounding blocks, and Buttercup, Brûlée, and Martini Lounge give that project something real to point to. But if you're the kind of resident who likes to plan a weekend around what's actually open rather than what's been announced, treat the ice cream shop and the Japanese lounge as things to watch, not things to build a Saturday around yet.
What's Actually Open This Weekend
The corridor you can walk right now, without waiting on anything:
- Martini Lounge, 1520 S. Wabash Ave., open 5 p.m. to 2 a.m. Thursday through Sunday. Twelve martinis, a short cocktail and wine list, a few bar snacks. Idonije has invited some of M Lounge's old DJs back for Friday sets, and the room recently hosted a release party for musician Marcus Kentrell Brown's single "Nobody."
- Buttercup, 75 E. 16th St. Coffee and pastries by day, cocktails by night, seven days of the kind of dual identity that makes it easy to stop in twice in one afternoon.
- Brûlée, 2036 S. Michigan Ave. A different owner, a different block, the same instinct to build something that didn't already exist a mile north.
None of this requires a car or a trip out of the neighborhood. That's the actual shift here. For years, a decent night out from a South Loop address meant crossing into the Loop or heading north. Idonije said as much to Block Club when he described the neighborhood as having been treated like "the stepchild of these neighborhoods, kind of an afterthought, despite being the heart of the city." Whether or not you'd put it in those terms, the math on your own Friday nights has probably borne that out.
The Delay Is the More Useful Fact
It would be easy to write this as a simple reopening story: bar closes, bar reopens, go say hi to the Miles Davis portrait. But the gap between April's stated June target and September's actual opening is the detail that tells you how to read everything Idonije has floated since. The hotel on Motor Row is real, funded, and permitted around an actual building. The timeline attached to it is not something to hold anyone to. The same goes for the ice cream shop and the Japanese lounge.
What you can hold onto is that three separate operators, none of them chasing a comp report from somewhere else, have now bet on this six block stretch within the past year, and two of the three bets are already open for business. That's a different kind of evidence than a press release about a future hotel. It's also the kind of thing that tends to keep happening once it starts.
If you've been in the South Loop long enough to remember when M Lounge was just M Lounge, this fall is worth a visit back. If you're newer to the neighborhood, you're getting the corridor at a point where you can still watch it fill in rather than arriving after the fact.
If you're weighing what any of this means for your own address on this stretch of Wabash or Michigan, Camille Canales Group tracks how these kinds of openings show up in what buyers ask about block by block, and we're glad to talk through what it looks like for your specific building.
