The happy hour is legit, especially if you're on a budget but there's not much inventive about Ra's menu, decor, or dining experience.
I will say that I've never had bad service at any Ra, which speaks to a pretty good corporate structure and training program. Water glasses are always filled and if there's ever a problem with the food or drinks their people are quick to remedy the situation.
The music is generally pretty decent. Eclectic mix, with everything from Biggie and Beasties to Ramones and Zeppelin. Can skew a tad loud though.
If you're looking to blow off some steam after work Ra is a solid option. And if you're with a gal, she'll more than likely approve.
