There is also the new Tusker House buffet. Supposedly it's similar to Boma's. We made an ADR for Yak and Yeti this summer -- I love the pics of the interior -- and there is a gift shop attached !
I wouldn't hold onto any negative reviews of Yak & Yeti right now. It is always hard to start a restaurant; lots of kinks and surprises, lot of staff turnover, etc. I'll give them 6 mos, may be a year before I think their reputation can really be established.
PP that's not to suggest you need to return, but I've been through those rough times at a restaurant, it's hard. The key will be for them to agree that things need to be adjusted or fine tuned so they can hit their stride.
