Have you been there lately? Completely redone-more upscale less kidafied. Gone is the loudness, carnival games, and bright colors. There is now a divider between the bar area and the dining room. The bar is full with new drinks and brews as well as flat screen tv's for sports viewing.
Still have great burgers, bottomless fries, and a ultra-friendly waitstaff. This a large restaurant with many booth and tables. So even though it's always crowded you can usually get a table quickly. Be sure to join the Red Robin club-get a free burger after 12 purchases, and a free burger on your B-day.
