Ah, Mr. Tofu. The sundubu here was good and has a flavor that is slightly reminiscent of a seafood broth, even though I ordered mine with pork. It's probably the nori strips they garnish with.
The broth here at Mr. Tofu is thinner than what I am used to, and it arrives at the table with the egg already in it, which for me, meant an overcooked egg. I like to mix in it just when the whites have almost set, but the yolk is still runny. They also don't have a kimchi sundubu option if I recall correctly. The banchan here is good but they didn't have any potato salad, which is a shame because korean potato salad is a thing of beauty.
Overall, this is a good place for sundubu although I prefer another place a couple doors down in the same plaza. I would come back to try their chicken soup though.
