try Luxe, its located right next door to Union Station and RiRa.
BYOB aka Build Your Own Burger for $6.99, and they have kobe beef and tuna, lots of kick a## burger toppings. Cheap Narragansetts and draft beer. Plus theres some eye candy that works there.
Great food at an affordable price. Walking distance from the show too.
keep in mind that the NCAA Basketball tournament is going on Saturday 12 to 8pm and there is also a Mary Kay Convention all weekend, sounds like cougar hunting season opens early this year.
