Little food cart just south of the SW corner of Yonge and Finch, located right in front of the Shoppers Drug Mart.
They have an assortment of small portioned foods on sale for cheap prices, such as a rice cake for $1, squid skewer for $2, small portion of noodles, etc.
The item I believe they are most known for is their red bean-filled waffles, which come in the shape of a fish. They sell 3 of these for $2.50, or you can purchase a single waffle for a dollar. These waffles are made fresh when you order, and they are so popular that you will always see the staff making a fresh batch (they have a waffle maker that can make about a dozen of these fish shaped waffles at a time).
If you're looking for a quick, cheap snack and are on the go, Kim's is a great place to make a pit stop.
