Moti Mahal Barbecues is the best place for birthday parties in OMR. And, the best part about this place is their price range. If you are planning to visit a barbecue restaurant in OMR, you can call the restaurant, check the price, and book the table ahead of time. 

Finding the "best" place for a birthday party is subjective and depends on your specific needs and preferences, such as budget, the age of the birthday person, the number of guests, and desired activities. However, I can suggest some popular and well-regarded options in and around OMR, Chennai:

• Restaurants with Party Spaces:

  Many restaurants along OMR offer separate spaces or can cater to birthday parties. Consider restaurants based on the cuisine you prefer and their ability to accommodate a group. Contact restaurants directly to inquire about party arrangements.

To find the "best" option for you, I highly recommend:

• Checking online reviews: Look for recent reviews on Google, Zomato, and other platforms to get an idea of other people's experiences.
• Contacting the venues directly: Call or email the places you are interested in to inquire about their party packages, pricing, availability, and any restrictions.
• Visiting the venues: If possible, visit the venues in person to get a feel for the atmosphere and see if it is a good fit for your party.
