8:55 AM PT -- Sources close to the situation tell TMZ ... Tristan showed up alone to the restaurant and he exchanged hugs with Kim when he saw her. We're told the embrace was cordial ... Tristan actually sat down with her crew and hung around for a bit.
Our sources say even though Khloe's not with Tristan, they consider him family because he's Khloe's baby daddy. We're told cameras were rolling for 'KUWTK.'
Kim Kardashian hit up one of the more than 30,000 restaurants in NYC ... and somehow her sister's ex, Tristan Thompson, ended up there too.
Kim and some buds -- La La Anthony and Jonathan Cheban -- hit the town Wednesday night and ended up at arguably the best seafood place in the city -- Milos. Unbeknownst to her, Khloe's ex was also in the mood for a little surf action.
Smart bet says they did NOT break bread together. Kim left the restaurant arm in arm with La La .... while the NBA star kept a low profile with a hoodie.
Seems the whole gang was there for New York Fashion Week, which ended Wednesday night.
Unclear if Kim still harbors bad feelings after Tristan cheated on Khloe with Kylie's BFF (and that other time too). But, at the very least, they can tolerate catching fish at the same joint.
