Since my brother was the one whom went to queue so I don't have the photograph of the place. Well, at the least I managed to find out the name of the place and here's the plastic bag with the address.
The portion is really small and I think this is already the large portion. Noodles are good but it's pretty dry.
If you're nearby then try it but be prepared to queue for it under the hot sun. Else, maybe you could just try something else like Phai Thai or what if you're not a fan of wanton noodles. For me, it was pretty good, I like Wanton Noodles in general.
This is their address:
4/32-33 Soi Petchburi 19 | Pratunam,Bangkok, Thailand
But have fun finding them because I really don't know where it is located except knowing that it's by some Alley and when you see a super long queue, that's probably it.
