Tony Parker & Eva Longoria -- Table for Two Exes

Tony Parker and Eva Longoria reunited for a lunch date in L.A. on Wednesday -- two weeks after she filed to divorce him in Cali ... which was followed by Tony's own filing in Texas.  Awwwwkward. 

They met on neutral ground ... at a hotel in Santa Monica. Tony was in town because his San Antonio Spurs played the Clippers last night -- but based on Eva's gestures and Tony's expressions ... we're guessing there was little hoops strategy discussed.

No lawyers were present to split the bill.
