I have been to Gyubee a few times and each time I leave satisfied.
Each time I have arrived, I never had to wait more than 30 minutes for a table.
The food is great and the service is wonderful every time. Unlike a lot of Asian restaurants, the servers ask how your meal is and if the food is okay throughout your experience.
I also love the variety of cuts of meat you can choose from and it does not compare to Chako or Korean Grill House (both of which are the closest AYCE BBQ). There are also a lot of side dishes to choose from. They also have unlimited bibimbap for order! The best part is the Melona at the end of the meal.
However, the downside is the MSG. I believe it is only found in the bean sprouts, marinated beef and the seasoning on the table. I am parched each time I leave the restaurant and feel as if I had just woken up from a night out.
Overall I am very satisfied with this restaurant and would always recommend :).
