"Bucket Dining" Kashmiri-Style -- A growing phenomenon, which we can only call the Birmingham Balti Experience, may interest those who love spicy food. Balti literally means bucket, but it refers to a Kashmiri style of cooking over a fast, hot flame. With the city's large Kashmiri population, there are now many baltihouses in Birmingham, most of which are bare-bones, BYOB affairs. One of the better ones is Celebrity Balti, 44 Broad St. (tel. 0121/643-8969; www.celebritybalti.co.uk), close to the Convention Centre, which is open daily from 6pm to midnight.
