Guinness-certified as the world's oldest vegetarian restaurant (established 1898), Hiltl proffers an astounding smorgasbord of meatless delights, from Indian and Thai curries to Mediterranean grilled vegies, plus salads and desserts. You can opt for the buffet (charged per 100g) or for more substantial mains. Sit in the informal cafe or the spiffier adjoining restaurant. Good-value takeaway service is also available.
