Although I try not to echo my fellow Yelpers' previous reviews, I'd like to echo my fellow Yelpers' previous reviews. This place is most definitely an uptown "institution". I think pretty much every Jew in Toronto has eaten here at least once, or continues to eat here regularly, with or without their bubby and zaida (usually with).
Highlights for me at United Bakers--aka United Dairy, aka "United"--include the tuna (def one of my favourite tunas in the city) and the famous split pea soup (heartwarming)...other great bets are the Greek salad, the noodles and cheese (served hot), and the eggplant parmesan. They have nice baked goods as well.
Oy vey that's a good Jewish diner!
