We've enjoyed coming to Miga many times and always go for the BBQ at the table option. The meats are always of excellent quality and flavour. It would be nice if the portions were a little larger for the price, but at least they do keep bringing side dishes, rice, and lettuce as much as you want without charging more. Spicy Pork Bulgogi is our favourite but we also order both marinated and un-marinated galbi and premium steak.
One complaint that comes up nearly every time we visit is how often they want to change the BBQ grill top. It varies by visit but often they won't let you go more than 15 minutes using the same grill. The last time we visited, we hadn't even finished cooking our first round of meat before there was a guy at our table insisting we change the grill (like 5 minutes of cooking... we refused to let him change it). There are three problems with this. 1) changing the grill too often means you have to wait for the grill to reheat every time (food takes longer to cook) 2) you lose the extra "BBQ flavour" of the meat (the caramelized sugars of the marinades) and 3) there's always someone hovering around the table. It's just annoying and we'd be alright with changing the grill between each type of meat but lately it's constant harassment, even when we send them away.
Even though we hold off on the grill changes, the food still tastes great. I just wish when customers expressed disinterest in this process that they would back off more.
