Thin body with decent roast character. The finish is bitter but sort of tastes like a hoppy bitter?

Pint at the brewpub. It's a dark, dark brown--virtually opaque black--with finger-width almost nitro looking creamy light brown head with no lacing. Aroma is straightforward roasted malt and chocolate with mild berry component. Taste is sweet/tart blueberry, roasted malt base. Mouthfeel is light side of light-to-medium bodied with thin texture, soft carbonation and finish as taste. Overall, don't love the berry component. A bit thin.
