I used to come here for work lunches all the time, but I will never come back to this or any Red Robin. Maybe it's completely freaking irrational of me to say that, but I had a bad experience here and I don't want to take the chance that it might reoccur.
I got one of those burgers with the fried onion strings on it, but on this particular burger it was like they fried a whole onion, without slicing it, and slapped it onto the burger. I bit into it and a huge clump of onions ended up in my mouth. Rather than spitting it out and making a huge ass of myself in a crowded restaurant, I chewed on it for about 10 minutes, trying desperately to mince it into smaller pieces so I could swallow it without choking or gagging, while my girlfriend laughed at me. When I finally forced it down, I was so grossed out I didn't even want the rest of the burger.
You may have a better experience! In fact, you very likely will! But I will Red Robin no more forever.
