Christophe Berra scored the second of his two goals in stoppage time to secure a 2-2 draw for the visitors at St Andrew's, but Clark believes that the performance from his players was promising once again.
"It was a frustrating finish. I am gutted for the players. We deserved another victory," the Birmingham boss told members of the media. "It would have capped off a brilliant week at home - three wins on the bounce.
"We cannot be too downhearted as the players gave another terrific performance. Ipswich are a powerful team, and they will do a lot of damage to teams over the course of the season.
"I am absolutely delighted with what I've seen, but devastated for the players who didn't get what they deserved."
Birmingham are currently 15th in the Championship with four points from their three games.
