Funny...I was just having this conversation with someone yesterday! We were discussing Langosta Lounge and I said that while I've only been there a few times (and that I understand the concept--the menu represents places/dishes from the owner's travels), I feel like the menu says "We're not sure who/what we are as a restaurant." I've had a few meals there and they've all been just okay, and I suspect that part of the issue is a lack of focus. If your team needs to cook Thai, burgers, sushi, Italian, etc., etc., etc., chances are good that they may not excel at any of them. That's MY opinion... But when my friend said on one visit their burgers were great and on the next, notsomuch, well, I rest my case, yerhonor.
[Sidebar: I recently had a dish there that really wowed me; a Thai winter squash and green apple soup that was EXCELLENT. I don't say that lightly, as I make some damn good soups and have learned how to do soup in general. But then the sandwich was...just okay.]
