Ilona Andrews can be enjoyable - They started off their Kate Daniels series with no intention of it being considered "romance" , although as is the nature of any long-running series of books the relationships between characters can become plot elements.
What's kind of amusing is that because the books would keep getting put in the romance section of book stores before "Urban Fantasy" got its own section, they ended up writing a few romance urban fantasy stories just because people thought they already wrote them.
You might like to try Simon R Green. He's done both a fantasy world style urban fantasy in his Hawke & Fisher, while his Nightside is very much that otherworldly realm in the center of London where fantasy and reality share renting space and the sun never shines.
Jonathan Moeller's Cloak Games is kind of the Dresden Files meets Shadowrun, set in a near future earth where Elves invaded from another Dimension and are firmly in control. The story of one woman trained to be a covert thief / agent for a manipulative Elven High Mage.
Depending on how much pulp you like, (and swerves into sci-fi), check out Michael Todd.
And if you like both humor and spice, check out Elliot Kay's Good Intentions trilogy - The guy just finished high school, starting college..and ends up bound to an Angel and a Succubus at the same time, finding out that life is a whole lot more complicated then he ever realised.
