Check Whether a page is using WordPress Custom Taxonomy Category

Well, today i faced a little problem on checking whether a page displaying on WordPress site is using a custom taxonomy post type. I need to determine whether that particular page is using a custom taxonomy post type and that particular page is using a particular custom taxonomy post category as well. In this case, i search a bit but couldn't find this answer easily which resulted me to write this in the case i need this in the future as well.

In order to find whether a particular page is a custom taxonomy category type, we test with the following sentence

 if(is_single()){
          } else if(is_tax('reviews', $term = 'Games')){
            $args = array( 'post_type' => 'reviews', 'showposts' => 72, 'tax_query' => array(
		array(
			'taxonomy' => 'review_category',
			'field' => 'slug',
			'terms' => 'games'
		)
            ) );
          }else if(is_tax('reviews', $term = 'Apps')){
            $args = array( 'post_type' => 'reviews', 'showposts' => 72, 'tax_query' => array(
		array(
			'taxonomy' => 'review_category',
			'field' => 'slug',
			'terms' => 'apps'
		)
            ) );
          }else
            $args = array( 'post_type' => 'reviews', 'showposts' => 72);

My custom taxonomy is 'reviews' and i wanted to check whether a particular page is type 'Apps' or 'Games', this way i am able to determine whether the particular page is using a custom taxonomy category which is different from using is_category which check post category.
