It is quite nice. There are two exhibits of roughly the same size - one for Sumatran and one for Malayan. There is a large indoor (and air conditioned) viewing room with huge glass panels on either side, plus tons of outdoor viewing. It does rank among the better I have seen, though as a fan of giant spaces for animals I would like it to be even bigger. Let me see if I can list off the top of my head the only tiger exhibits I have seen that are even better than this...
Minnesota Zoo (Siberian race)
San Diego Safari Park (Sumatran race)
Le Parc Des Felins (various races)
Dallas Zoo (Sumatran and Malayan races)
Highland Wildlife Park (Siberian race)
