If you're looking for a good quality, quick, and damn cheap Vietnamese meal, then Tay Do is for you.
I can admit that it's not michelin star quality food but in saying that, I've never been to an exquisite Vietnamese restaurant...nor heard of one (unless someone can "Tip" me in the right direction). Overall, the food is very good and this well-oiled machine restaurant will bring it to you within 10 minutes of ordering.
If you pay more than £8 per person, that is because you ordered a soft, drink, 2xentrees and threw a tip in for good measure.
Enjoy!
