I wonder if concierge from luxury hotel truly makes a difference in terms of dining reservations.

About 3 years ago, I went on a Japan trip and stayed at the Sheraton Tokyo and the Westin Osaka, and between those two hotels, they got me reservations at 9 different micheliM restaurants, including 3* Yoshitake, 3* Kichisen, 3* Fujiya 1935, 3* Esaki.....so I'm wondering if time of the year and luck has more to do than the hotel concierge.

But regardless, this time around I am hoping to stay at more "upscale" properties...and hope their concierge can help me get some more hard to get reservations.
