Hi
Go up to Glasgow a few times a year (daughter in uni there). Always for her birthdays and usually on one other occassion a year we go to www.yenrotunda.com to the Teppanyaki (although we have been to the Oriental restaurant which is nice but doesn't stand out like the Teppanyaki).
No it's not the cheapest place to eat but the food is always excellent and combine that with being entertained by chefs cooking the food in front of you it's an evening of fine food and fun entertainment and it comes highly recommended.
