3 /5 LaShumbra Singleton: The atmosphere is nice, particularly on live music nights. It would be nice to have more vegetarian food options. The seating has improved with the reopen, and they have a lot of staff. The restrooms could be monitored a little better, but at least all of the stalls work. My main concern is Duos mandatory 20% gratuity on all bills. I am a great tipper, especially when the service is great. At Duos, Ive had phenomenal service, and I tipped 30-35%. And there were times when the service was so poor that I didnt get water, or wouldnt see the staff for more than half an hour or would have wrong orders and poor communication, and their mandatory 20% tip would not reflect their work performance. Tipping is a reflection of ones professional effort and should not be mandatory.
