First of all, the restaurant's A/C wasn't working properly since it was quite warm (even muggy.) The server welcomed us briefly and took our order a few minutes later. We waited for over 15 mins until we had to ask another server to bring our drinks and she apologized for her fellow server's mishap. While all of this was taking place we noticed our original server was having a laugh (flirting) with a fellow coworker.
The burgers weren't that good but the fries were very good, though. A tip, order the small version of the burger of your choosing since it's actually quite big. I wouldn't imagine having the large sized burger, unless I haven't eaten for a day or two.
Maybe I had bad luck with my server and the joint's temperature control, but who knows it could be business as usual at RBT. Will not be back in a while.
