3.5*
A pretty solid option for pho in the Yonge and Davis area of Newmarket (where pickins' are slim). Located in one of many plazas along Yonge street, Second Bowl is a decently sized restaurant that serves a selection of Vietnamese and Thai dishes.
I had the large pho with rare beef and beef balls ($8.50) - the garnishes were fresh, which is a good sign that the restaurant does have enough business that there is regular turnover for their produce. While the broth wasn't the best I've ever had (Pho Metro in Scarborough has that spot in my heart), it was clear, not too fatty, and has little/no MSG in it, judging by my level of thirst afterwards. The large size was enough to give me that satisfied/full feeling I look for whenever I have pho.
I also had the iced espresso + condensed milk over ice ($3.99). While not particularly memorable, it still hit the spot.
I'd give 4* for the food alone, but the service knocks it down half a star - while it wasn't unfriendly, I do think the service could be friendlier.
