My friend's birthday has come and gone now and I can safely say that we were wildly underwhelmed by Between Boutique. I should paid more attention to jn2001's warning.
I arrived later than I anticipated and not hungry, so I didn't try the food. My friends who did eat were generally positive and enthusiastic, though the plates were rather over-priced for what you got.
The drinks, though, were a complete disaster. One friend was saying that they only recently got their liquor license, but unless they received it that morning, there's no excuse for serving only Heineken and Miller Light. When someone asked for a whiskey, the only option was Seagram's. I steered clear of the mixed drinks because there was no drink list available, and the drinks that I sampled were sub-par (case in point, a pinot grigio spiked with pear brandy cocktail... it was... barely drinkable). The Rum Bubble Tea drink turned out to be the worst drink she ever tasted, too.
Our server seemed ambivalent, bordering on annoyed that we were there at all. We were a large group, and people were ordering food and drinks at different rates. But with such a focus on small plates, and it being a lounge, I feel like that should be expected. The chef came out to ask how we were enjoying ourselves, and we lied because we felt bad.
The room was empty, and not just in terms of people. It felt sparse, and unfinished -- cold, too. It's been open for 2.5 months, but you wouldn't know it to walk in.
Granted, they're on a tough stretch of Milwaukee, one that has only recently begun to show the same amount of life found near North and Damen. But that excuse can only let them get so far -- look at Schwa, a restaurant that found great success despite being a little off the beaten path; or even The Violet Hour, a room that is certainly sparse, but hardly cold or uninviting.
So, until they stock their bar appropriately and maybe re-vamp their concept to be less lounge-y and more restaurant-y, I don't think I'll be back.
