If you are a vegetarian and looking for some buffet restaurants near me to taste lip-smacking vegetarian dishes, you can go to Moti Mahal Barbecues. In my experience, you can get decent options, and you will love their vegetarian sections.  

Finding the "best" restaurant is subjective and depends on individual preferences. However, here are some highly-rated vegetarian buffet restaurants in OMR, Chennai, based on customer reviews and popularity:

• AB's - Absolute Barbecues
  • While not exclusively vegetarian, AB's offers a substantial vegetarian buffet with a wide variety of options, including grilled appetizers, main courses, and desserts.
• Copper Kitchen
  • A popular choice for vegetarian buffets in Chennai, Copper Kitchen has several outlets and is known for its diverse menu.

To determine which is best for you, I recommend:

• Checking recent online reviews on platforms like Zomato, Google Reviews, and TripAdvisor.
• Looking at menus and photos to see if the buffet options appeal to your tastes.
• Considering your budget, as prices can vary.
• Checking for any special deals or discounts.
