A year ago Capital One launched a relationship with dining reservations site Resy, setting aside tables at great restaurants for cardmembers. American Express went and acquired Resy and now American Express has a much weaker Resy partnership. Capital One quickly went out and partnered with OpenTable.

Yet somehow I didn’t even realize that before these things happened – a full 19 months ago – Chase launched a partnership with restaurant booking site Tock, which sells tickets to restaurants (top end restaurants with limited seating charge you in advance for pre fixe meals through the site).

For the first time I stumbled upon this when I was making a dining reservation in Chicago at Smyth.

Booking far out into the future most times were still available, but 6 p.m. on one particular night was only available for Chase customers.

These tables show for everyone, but since meals are prepaid the way they restrict this to Chase customers is by requiring payment for these times via ChasePay. I had actually never registered for ChasePay before. (And Chase is killing the standalone ChasePay app though it will remain a payment option through other services.)

All I had to do was log into my Chase account during the checkout process and select the Chase card I wanted to pay with. There’s also an option to pay with Chase points, which I didn’t take them up on.

I knew about special Sapphire Dining events but never about the restaurant reservations set-aside. Fortunately it’s not a secret trick you need to know about, when it’s an option it’s displayed to you. It’s just only an option at certain restaurants that book through Tock.
