Clinton St. Baking Company on the Lower East Side makes the best pancakes in the whole entire world. They come with this maple-butter that is so decadent and delicious. THEY CAN'T BE BEAT! seriously, try them.
Veselka's pancakes can be pretty good, but I find the best pancakes 9 out of 10 times are at La Bonbonierre. Veselka's "fresh" raspberry sauce can sometimes be partially unthawed, but still it's yummy.
