After the promising earlier post here about the great and cheap ramen at Double Happiness I ventured there myself. Easily off of Bathurst subway on Bloor.
Inside is very 'small-hall-turned-restaurant' and is more like a corridor, but it's certainly clean and the staff were cheerful enough. At 1:30 PM it was busy with about 5 tables occupied (more than 1/2 the restaurant).
The ramen is on the front in a banner, but not on the menu itself. I initially ordered beef noodle soup from the menu and had to correct it immediately to ramen. They have a seperate small menu of four ramen (with large photos!)
I got the tonokotsu (don't remember spelling) for takeout and it was packed in two containers: noodles and soup. When I brought it pack home was quite happy because the noodle amount is quite generous, with sprouts and 3 delightful little squid balls that were sweet. The beef was thinly sliced with just a slight edge of fat that was delicious. The soup base was ramen to me and I thought it was good (My experience with ramen is limited to about 3-4 places in Toronto).
The best thing was VALUE. The noodles cost 5$ and that included a pop. The portion is very generous, both beef and noodles were more than Konnichiwa which puts their takeout noodles and soup in the same containers which is not ideal for transport. The Konnichiwa soup has a slightly cleaner and richer taste while the the Double Happiness soup was good but definitely had seasony-MSG tones to it.
I will be definitely returning as it's relatively convenient (if it was along Yonge I would probably go every week). The staff were friendly, it's inexpensive, and it gives me an excuse to go to that Korean supermarket nearby for cheap cup noodles (the irony of hunting for authentic delicious ramen and then buying instant noodles as I wait for it is not lost on me).
