The burgers were average, huge and relatively satisfying. I'm not a major fan of steak fries but they were good too. Service was mediocre. I'm not sure why but we always had to ask to have the fries refilled. I thought it was bottomless, it's kind of uncomfortable to continually have to ask your server three or four times to get your money's worth.
Sidenote, but it was through the greasy deliciousness of Red Robin that my girlfriend finally found out she had a stomach ulcer. The night after we ate it she ended up in the ER with intense stomach pain. Bottomless steak fries aren't messing around, people! I'm not sure we'll be back anytime soon, given her affliction!!
