TL;DR: Don't bother. There are better options in Toronto to spend $25-30/pp on. Good food and terrible service. Limit/take away the food then why bother?
We've been going there for over two years. I loved Jang Wons. It was a pretty good All-You-Can-Eat Korean BBQ place that eclipses the standard KBBQ places that Torontonians are used to (Korean Grill House...). The place does not have the best ventilation and you always leave smelling like bacon (depending on who you ask this may be a good thing). As an honest disclaimer, we usually suggest going for here for the food not the service.
For background, this place runs on a 'you don't get more food until you provide empty plates' policy to reduce food waste (understandable) . It always seemed like we were inconveniencing them when asking for service though. With an imposed 2 hour limit, the nature of their business is to moderate the customers consumption and the expectation is that customers would want the most out of their time if the service kept up. But when you flat out ignore customer requests for more food when they are empty and limit the meat available to that of a la carte quantities. That is ridiculous!
We've accepted the fact that they removed the service buttons because they couldn't keep up, we've accepted the fact that they've removed the shrimp paste they use to provide and we accept the fact that service is slow. However, when you slow down the service to a halt and provide little to no food before cutting your loyal customers off. (we've gone here for two years!) That is unacceptable.
Our most recent visit a few days ago has disappointed us so much that we have left this single star review. We will not be going back and will no longer recommend it to our friends.
The story for those interested:
I got a table for 5 and sat down before the rest of the group came. I told the waiter we were getting the number 4 which included beef and the bulgogi dish because one of our friends could only have beef.
As we all started the dinner, it was the usual slow service despite the restaurant being relatively empty (2 other tables). We had to spend most of our time chasing the waiter and presenting them with our empties to get our next serving. At this point we were only on our second plate of meat (keep in mind this is 5 people) and needed a variety of things from water, new butane for the stove and more meat. We subsequently asked for another serving. To our dismay, the waiter said we had been cut off as we had passed the 2 hours. They started the time the moment I sat down when the table they provided had not even been cleaned!! As a last ditch attempt to get more food (we were starving), we asked for the bulgogi which is provided at the end of the meal since it's a separate dish. The exact words from the waiter: "no, the owner said you can't have anymore. Owner says bulgogi is part of the all you can eat meat and you been here for two hours ". There was no last call warning and the two hours starts as soon as you sit. Not when you get food.
