We ordered the Bottomless Root Beer Float and a burger with so-called endless fries - GUESS AGAIN.
After one root beer float, they suddenly had no more of the featured mugs they advertise that they come in and shifted to a small glass at least 1/2 the size. The restaurant was half full at 8 PM on a weekday, and they claimed they ran out of glassware, hmmmmm. The endless fries got one refill for two of us, and then the wait staff just disappeared.
When we finally cornered our waitress and asked for another refill, she said she would take care of it, and after a long 15 minutes we got our last refills.
If they advertise something, they should serve it. As a former pro football player, I do have an appetite, but to have deceptive service of avoiding refills we will NEVER go to Red Robin again.
In hindsight, we could have gone to In-N-Out Burger for half the price and had a more delicious and satisfying dining experience.
