I love the atmosphere in Boltini - it's an amazing place to just relax and have a few drinks with friends over some food. Inside is dimly lit with strategically placed candles and intriguing local artwork hung throughout. Intimate booths up front for a date night and plush couches in the back for larger groups - I'm a fan of both.
Drinks are priced relatively high for Champaign-Urbana standards at around $7-10 a cocktail, but they are made strong and well so it's worth it in my opinion. Food there is alright - I'm trying hard to remember it but failing ... which means it must not have been that spectacular.
Summary: Go to Boltini if you want to get away and relax in an intimate setting. Not if you wanna get wasted and start dancing on the tables. Go to Joe's or Murphy's for that.
