Ok thanks guys. I called yesterday, and they told me that they could book us, but that we couldn't sit together.
1)
Listen to the ressie people in this case.
2) HDDR has a different seating method than other eateries.
. . . they have large tables (6-8 people)
. . . they have medium tables (4-6 people)
. . . they have small tables (2 people)
3) They have only so many tables they can push together.
4) If they get pre-sold to others, then you get split up.
. . . HDDR gives out tables in the order they are sold
. . . other eateries give out specific tables when you arrive
. . . with other eateries, they can take some ADR's and postpone them
. . . this gives them a chance to push tables together
. . . with HDDR, all tables are sold in advance
. . . so, no chance to push together pre-sold tables
