Came here on a busy Sunday afternoon during service. It was packed, but we only waited a few minutes for a table.
The building is huge and relatively ornate (this ain't Zen), the incense is lovely and the followers are kind and mellow, mostly Chinese (a lot of rich Mississauga followers helped pay for that temple).
You need to buy coupons at a table (in cash) before entering the restaurant, which is clean and humbly decorated.
We had two delicious vermicelli and mock meat soups (vegan) and lovely oolong tea.
Many items have dairy, so be aware and ask if vegan.
Will definitely go back.
