Anil is the leather guy at Rodeo Drive (no kidding) over at the Oberoi Towers. Gary is the jeweler also at the Oberoi Towers. You'll have to get a ride over there from the Leela or the Sheraton, wherever we're staying now. It'll take 45 mins to drive and since it's your first trip, it'll take several years off of your life too.
Anil measures you for your jacket, makes it, and will deliver it to your hotel in about 24 hrs. Mine was around $120 a few yrs ago. Gary will show you everything in his store and might even take you to lunch. He can custom make jewelry but you'll have to return to pick it up. Gary has VERY nice things.
