僕は行ったことがあるけど、そんなに評判ほどのところじゃないよ。

、。

I've been there, but it's not as great as its reputation suggests.

Literal

I [topic-は] went-[experience-ことがある] [but-けど], that-much reputation [extent-ほど] [possessive-の] place [copula-じゃ] not [insistence-よ].

~たことがある marks past experience. けど links contrasting clauses. 評判ほどのところじゃない — 'not a place as [good as] its reputation.' ほど sets the benchmark, and the negative says reality falls short. そんなに~ない ('not that much') reinforces the shortfall.
