Looking for a Reliable Mechanic to Restore My BS3 Classic 350 in Thiruvanmiyur - Injambakkam Area

Since the service centers for Royal Enfield are mostly subpar, are there any local mechanics or shops that provide great service for Royal Enfields? I own a BS3 Classic 350, which hasn’t been ridden for at least six months. I need to restore it to a running state. Can anyone help me with this? Are there any good shops between Thiruvanmiyur and Injambakkam?
