The best restaurants serving Vietnamese food in Castle Tamworth West Midlands

We visited yesterday for the first time, and decided to have lunch. It was really busy. I ordered gammon, egg and chips, which was supposed to come with onion rings, but there wasn't any, and no explanation as to why I didn't get them. The egg was hard boiled rather than fried, surely it's supposed to be runny... My partner ordered fish and chips, was under seasoned and batter was soggy. No one came to ask if our meals were OK, so not sure we would visit again. However the bar staff were friendly, so no complaints there.
