All of the June times are posted online. If it is blue and allows you to select it, they are taking reservations for that day. It looks like they are sold out online already. Depending on when you are going, you can try to get something in July, which is not yet posted. If you are going earlier in June, I suggest calling. Sometimes you can get ADRs by calling that are not available online. This may be due to immediate cancelation access by phone but not online. I am not sure. They try to post 180 days in advance like other restaurants but do not always have the schedules ready in time. That is why there are no posted dates for July or August yet. If it is grey, you cannot book that date by phone or online even if it is less than 180 days from now. Good luck. I want to go on my next trip too, so here's hoping we both get in.
